Question

Find the breadth of rectangle whose length is 12 cm and perimeter is 38 cm
​

Answer 1

Answer:

${\sf{ \rm{\blue{ Breadth = 7cm}}}}$

Step-by-step explanation:

We know that Perimeter of A Rectangle:-

${\sf{ \rm{\blue{Perimeter = 2 \times (Length + Breadth)}}}}$

Now, substitute the value of Length and breadth in the equation Perimeter = 2( Length + Breadth)

${\sf{ \rm{\blue{38 = 2 \times (12+ Breadth)}}}}$

${\sf{ \rm{\blue{\dfrac{38}{2} = 12 + Breadth}}}}$

${\sf{ \rm{\blue{19 = 12 + Breadth }}}}$

${\sf{ \rm{\blue{19 - 12 = Breadth }}}}$

${\sf{ \rm{\blue{ Breadth = 7cm}}}}$

Answer 2

Answer:

${\sf{ \rm{\green{ Breadth = 7cm}}}}$

Step-by-step explanation:

We know that Perimeter of A Rectangle:-

${\sf{ \rm{\red{Perimeter = 2 \times (Length + Breadth)}}}}$

Now, substitute the value of Length and breadth in the equation Perimeter = 2( Length + Breadth)

${\sf{ \rm{\blue{38 = 2 \times (12+ Breadth)}}}}$

${\sf{ \rm{\blue{\dfrac{38}{2} = 12 + Breadth}}}}$

${\sf{ \rm{\blue{19 = 12 + Breadth }}}}$

${\sf{ \rm{\blue{19 - 12 = Breadth }}}}$

${\sf{ \rm{\blue{ Breadth = 7cm}}}}$
